Anybody used Alliant's Black MZ for cartridge loading? Alliant says it can be used but they have zero information avaliable and I can't turn up anything searching the net, basicly what I would like to know is how would it compare to Blackhorn 209? I tried the BH 209 and really liked the stuff but the price is just too much for what it does, I consider the BH 209 more as a bulky smokeless than a BP sub. From what little info I can find the Black MZ is supposed to be non-fouling and "virtually noncorrosive" (their claim anyway) and if so it may have the desirable qualities of the BH 209 without the cost. BP is good also but there are lots of times when I had just rather use smokeless in my 45/90 and the idea of a bulky clean burning powder that will fill the case is appealing, BH 209 was really good in that respect.
